If you want DTD validation in the parser, you have to tell it to do "dtd_validation". Stefan

[lxml-dev] lhtml
by Ian Bicking 26 May '07

26 May '07

I really want to take all our HTML-related routines and put them into a proper package -- right now they are scattered all over the place. lhtml seems like a nice name for this. I thought it would be good to also place it on codespeak, but I'm not sure where. New top-level? In /lxml/lhtml/(trunk|branches|tags) ? -- Ian Bicking | ianb(a)colorstudy.com | http://blog.ianbicking.org | Write code, do good | http://topp.openplans.org/careers

[lxml-dev] Bug in objectify node[:].index
by Christian Zagrodnick 24 May '07

24 May '07

Hi, following little script fails at the last assert: ---------------------------- import lxml.objectify tree = lxml.objectify.fromstring( """\ <root> <a name="car">foo</a> <a name="car">bar</a> <a name="tree">foo</a> <a name="tree">bar</a> </root> """) trees = tree.findall('//a[@name="tree"]') print trees foo_tree = trees[0] assert foo_tree.get('name') == 'tree' parent = foo_tree.getparent() assert parent.tag == 'root' node_list = parent[foo_tree.tag] import pdb; pdb.set_trace() foo_index = node_list[:].index(foo_tree) assert foo_index == 3, foo_index # FAILS: foo_index is 0 ---------------------------- So, fo_index == 0. Which is <a name="car">foo</a>. Apparently the .index only looks at the text or something?! Anyway, all I *actually* want is to remove the nodes found by the xpath. The way you'd think it would be 'normal' doesn't work unfortunately: (Pdb) p parent.index(foo_tree) 2 (Pdb) del parent[2] *** TypeError: deleting items not supported by root element This is obviously because of the sort fo strange list/attribute handling (i.e. parent is parent[0]) But then there is parent.remove(...) which works. Apart from the bug above objectify feels kind of strange sometimes... :/ But then at other times its really nice again :) -- Christian Zagrodnick gocept gmbh & co. kg · forsterstrasse 29 · 06112 halle/saale www.gocept.com · fon. +49 345 12298894 · fax. +49 345 12298891

[lxml-dev] Resolvers not passed on to sub-documents?
by Sidnei da Silva 21 May '07

21 May '07

This might or might not have been fixed recently. I am using lxml 1.2. I'm writing a self-contained test for this. If you have a XSLT that includes another XSLT, which in turn includes a third one, the resolvers doesn't seem to be passed on. theme.xsl: xsl:import sub.xsl sub.xsl: xsl:import common.xsl The custom resolver I passed when parsing theme.xsl is used to resolve 'sub.xsl' but not to resolve 'common.xsl'. I remember discussing a similar issue, maybe this is a problem with libxml2? -- Sidnei da Silva Enfold Systems http://enfoldsystems.com Fax +1 832 201 8856 Office +1 713 942 2377 Ext 214

Hi Stefan, couldn't respond earlier as I have no svn access at work currently. I've tested your changes and they work just perfect for me. Find attached a little patch that adds some information on this topic to the objectify docs, and a test method also. Thanks, Holger

[lxml-dev] python crashes in xmlDictFree inside Zope

Thanks, I am using the latest "darwinports" version of libxml2, which I just updated -- this problem occurs with the version below. Note that this problem doesn't happen with the same code run from the python shell -- only on when used inside Zope.

[lxml-dev] Question o xpath
by Paul Eipper 20 May '07

20 May '07

Hello again :) I'm hitting an issue... hope someone can help me. Say I have this data: ***snip*** <file name="04_Rush_Hour_Wheels_of_Progress.mp3" size="5.51 Mb" time="Dec 13 13:36 2006"> <comment>6:1, 128 kbps#44100Hz, Joint stereo</comment> <mp3tag artist="Andy Brick" title="Wheels of Progress" album="SimCity 4 Rush Hour Soundtrack" year="2003"></mp3tag> </file> ***snip*** if I do a xpath search like this, I get a result: >>> o.xpath('//*[ contains( @*, "Andy" ) ]' ) [<Element mp3tag at 977940>] but if I try to search for this string: >>> o.xpath('//*[ contains( @*, "SimCity" ) ]' ) [] ...I get no result. Is the problem on the xpath query ? What am I missing here ? I thought " @* " is supposed to look at all tag attributes ? thanks, -- Paul Eipper Brasil
